STEP Labs technology uses the physics of sound propagation to define the shape and arrival time of sound waves to isolate voice signals from undesired noises. STEP Labs' software uses these distinctions to tell the difference between the user's voice and other voices, sounds, and noises, preserving the natural fidelity of the voice without distortion and producing near-perfect voice recognition performance, and impeccable noise cancellation.
